91 To this respect, we considered I148T, I175V, Q179K, and E193K in ICL1 (Seibert et al., 1997) and G970R in ICL3 (Seibert et al., 1996). Login to comment
100 This discrepancy was even more striking for I175V, which was associated with an anion transport rate greater than wild-type CFTR. Login to comment
120 The activity of I175V was also not significantly affected by potentiators, a behavior that further indicates that this protein is already totally activated with maximal forskolin and therefore behaves essentially as the normal protein. Login to comment
225 I175V may be another benign variant because its activity was comparable with or even higher than that of the native protein. Login to comment
228 Therefore, it is possible that some mutations such as I175V and I148T have a more profound effect on CFTR as a regulator of other proteins (Schreiber et al., 1999). Login to comment

106 However, only the mutations I148T, I175V, G178R, E193K, and R297Q allowed wild-type-like maturation of the protein to the fully glycosylated 170 kDa species (band C). Login to comment
120 In accordance with reduced levels of processing, the H139R, G149R, D192G, and R258G mutations significantly decreased the anion translocation capability of CFTR, whereas the properly processed I148T, I175V, and R297Q variants allowed iodide movement comparable to that of wild type.

190 I148T, I175V, and R297Q did not adversely affect the processing, gating, or conductance of CFTR. Login to comment
199 The entire CFTR gene was not sequenced in patients with mutations I148T, I175V, or R297Q when these mutations were published. Login to comment

DGGE analysis of exon 5 of CFTR, showing the familial segregation of mutation I175V: the parents (lanes 2 and 3) are heterozygous (presence of heteroduplexes formed between complementary strands of the two alleles); the two affected daughters (lanes 4 and 5) arc homozygous for the mutated allele, which is situated at a lower position in the denaturing gel than the normal allele (lane 1, control DNA).

297 For these mutations we performed an analysis with the NNS software and found that 3 of these sites were recognized as splice sites, but only 2 (the GU created by the I175V and the GU created by I1234V) had higher scores than the normal splice site (see Table S14). Login to comment
